I am going to guess that it is a faulty lift pump, if that is the case it will ruin the injection pump and they are expensive. so replace the lift pump.
is the ecm on a dodge 2001, 2500 diesel hard to replace??
No such part
AnswerYes if you have the moter mounts from the 2001 moter.
This is just a guess but No, everthing changed between those two years.

who ever said that a dodge ram diesel does not have a servo it is not true. I have a dodge diesel 2001 and it has a servo and the answer to this question is it had a vacuum leak in the servo vacuum line, changed that and cruise control worked great. the servo is under the drivers side battery.
In the side of the block,behind the starter.
It is under the dash on the driver side.
It was built with one.
